<p><P>PROBLEM TO BE SOLVED: To provide a transparent planar article and a transparent touch switch capable of improving visibility. <P>SOLUTION: The transparent planar article 1 has a patterned transparent conductive film 12 at one side of a transparent substrate 11. The article has a configuration including the transparent conductive film, an undercoat layer 13, a hard coat layer 112 and the transparent substrate which are laminated in this order from the side of the transparent conductive film, and coating layers covering surfaces of the transparent conductive film and the undercoat layer. The refractive index of the undercoat layer is lower than those of the transparent conductive film and the hard coat layer, and the refractive index of the hard coat layer is 1.60-1.80. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
